2.3 Ishikawa diagram In 1960s‚ Professor Kaoru Ishikawa has introduced Ishikawa diagram. This diagram also called fishbone diagram or cause and effect diagram (Ishikawa 1976). Since this diagram is inception‚ it has gained tremendous of popularity to identify the root cause of the variety of problems (Hossen et al. 2017). Besides that‚ Ishikawa diagram often called as fishbone diagram is because it can help in the brainstorming to determine the possible cause of a problem and also sort the ideas

An Introduction to Use-Case Modeling One of the primary challenges is the ability to elicit the correct and necessary system requirements from the stakeholders and specify them in a manner understandable to them so those requirements can be verified and validated. The hardest single part of building a software system is deciding precisely what to build. No other part of the conceptual work is a difficult as establishing the detailed technical requirements‚ including all the interfaces to people

Week 4 Assignment 2: Use Cases CIS 210 2-3-2013 There are a number of modeling tools and techniques that can be used to understand the design of a system. During this process‚ these tools and techniques can help to describe the business processes‚ requirements‚ and the users interaction with the system. One type of modeling is the functional decomposition diagram (FDD). It is similar to an organizational chart in that it uses a top-down model to describe the process. The FDD is a good way

Class Diagram A class diagram is at the heart of UML. It represents the core purposes of UML because it separates the design elements from the coding of the system. UML was set up as a standardized model to describe an object-oriented programming approach. Since classes are the building block of objects‚ class diagrams are the building blocks of UML. The diagramming components in a class diagram can represent the classes that will actually be programmed‚ the main objects‚ or the interaction between

BAR DIAGRAMS Bar diagrams are one of easiest and the most commonly used devices of presenting most of the business and economic data. These are satisfactory for categorical data or series. They consist a group of equidistant rectangles‚ one of each group or category of the data in which the values or the magnitudes are represented by the length or height of the rectangles‚ the width of the rectangles being arbitrary and immaterial. These diagrams are called one-dimensional because in such diagrams

Behavior Diagrams Definition: Behavioral models describe the internal dynamic aspects of an information system that supports the business processes in an organization. During analysis‚ behavioral models describe what the internal logic of the processes is without specifying how the processes are to be implemented. Later‚ in the design and implementation phases‚ the detailed design of the operations contained in the object is fully specified. Use case diagrams are behavior diagrams used to describe
